Artificial intelligence terminal intelligence classification — Part 9: Headphones
1 Scope
This document specifies the classification levels and level determination of key intelligence capabilities for headphones, and provides test methods.
This document is intended to guide the intelligence classification of headphones, including common forms such as over ear, in ear, semi in ear and open ear headphones, and also provides a reference for the design, development, application, selection and testing of artificial intelligence headphones.
2 Normative References
The following documents are essential for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition (including any amendments) applies.

3 Terms and Definitions
For the purposes of this document, the terms and definitions given in GB/Z 177.1-2026, GB/Z 177.2-2026 and the following apply.
3.1 sound pickup
The process of collecting sound signals through a microphone.
3.2 speech recognition
The process of converting human voice signals into text or commands.
[Source: GB/T 21023-2007, 3.1]
3.3 active noise cancellation
A technology that reduces ambient noise interference by analysing noise characteristics in real time, generating an anti phase sound wave and suppressing noise components.
3.4 environmental noise cancellation
A technology that improves speech transmission clarity in call scenarios by separating speech from ambient noise, identifying and suppressing non target noise components.
NOTE: Environmental noise cancellation is also referred to as call noise cancellation.
3.5 wakeup word
A word or phrase used by a user to wake up a device and initiate speech interaction.
3.6 host device
A device that can establish a connection with headphones, provide an audio signal source and control command interaction for the headphones, initiate connection requests, configure headphone parameters, and control related functions.
4 Abbreviations
The following abbreviation applies to this document in addition to those defined in GB/Z 177.1 and GB/Z 177.2.
MOS: Mean Opinion Score
